>>1155630>they don't "boil off".They do once you hit the boiling point of the fluid.
That also why larger calipers are a thing in faster downhill tracks.
Also MTB usually dont reach 100 km/h+ and stop with about 10m/s2, since energy is 1/2*mass*velocity sqared road bikes tend to put a much higher thermal load into their brakes than MTB do.
A large rider can put about 15 kW thermal load on his brakes when braking at high speed.
>The only need a bleed every year or two on a road bike.Depends on conditions.
>You need to spill several ML of oil to fuck up the pads.A few drops are enough to coat and contaminate them.
>I ride mine in -40 and they work fine.Yea, things don tend to overheat at that temperature...
>Keeping the pistons from sticking is relatively easy.Still requires you to remove the caliper or wheel...
>You really should own or at least try hydro discsI have hydraulic disc brakes on my MTB...
Only thing they dont suck at is braking in rain.
